The NACHI NU311EG cylindrical roller bearing features a 55 mm bore diameter, 120 mm outer diameter, and 29 mm width, constructed from steel alloy with a molded nylon (PA66) cage. It offers a high dynamic load capacity of 137,000 N and a static load capacity of 143,000 N, designed for single-row, high radial load applications. This open-type bearing provides low friction and long service life, suitable for precise shaft location in one axial direction. Its robust design and dimensions make it ideal for heavy-duty industrial machinery requiring reliable performance and durability. Voltage ratings and capacitance are not applicable to this mechanical bearing.
